The
following diagram illustrates a basic Cisco NAC architecture.
The OfficeScan client in this
figure has a CTA installation and is only able to access the network
through a Network Access Device that supports Cisco NAC. The Network
Access Device is between the client and the other Cisco NAC components.

The architecture of your network may differ based on the
presence of proxy servers, routers, or firewalls.
